What about PUTR and about a slew of other programs that
know alternate formats?

I realised out what you meant :-)

Hello, all:
I mentioned a while ago that I got these boards, and I actually received
them last week. To do a refresh, this board is an INS8073-based SBC with
lots of I/O in a compact 4x5 size. Someone mentioned that they may have
access to the manual but I can't find that message.
I need some info on these more than I thought. The kit comes with the board
and parts and nothing more. The silk screen on the board only has parts
designations (i.e., R1, C1, U1) but not the values. Some I can guess at but
not enough to make it work.
The only info that I have is on the 8073 specifically and not the board
itself. A search doesn't turn up much.
Any help appreciated.

What kind of juice do those chips need? 16 gauge seems awfully heavy for
any ICs I have worked with. I assume you know guages, but 16-18 guage is
standard lamp cord and will let you draw 5-10 amps on 110 volt. This
sounds good for a main power input to a transformer, but all ICs I have
worked with only pull at max a few amps at much lower voltages, so you
should be able to use much thinner wire.
I would check your amp requirements, and move to an 18 or 20 guage solid
or even higher if you can... phone station cord is usually 24 guage, but
don't mix it up with the 26 guage multipair cord... the usual obvious
difference is, station cord is 4 colors red/green/yellow/black....
multipair cord is 2 (or more) pairs of striped wire (blue, orange, green,
brown, slate all striped with white for the first 6 pairs)
But that aside, if you strip the standed cord, tiwst the strands in your
finger, and then tin the end with your solder iron (heat the end, and let
it draw solder into it, until it has a nice coat), it will be MUCH more
managable (although it still in general won't stay where you bend it,
other than the tinned end, lightweight alligator clips work wonders for
holding things in place).

I wondered about that. OK, it has to go, too.

I knew about that one; I didn't mention it before because I just took it as
read that I'd need to replace it :-)
Thanks again for the advice. Now all I need is time to get at it -- maybe
this coming weekend.

There's not much to tell, really. It originally belonged to the
University's Psychology Department, which has moved between buildings a few
times, and it was left in a small storeroom at the back of a building they
left some time ago. I bought something from a postgrad in the building,
and whilst chatting he mentioned that the AV technician was also into oold
computers, so I paid him a visit. In the course of *that* conversation, he
mentioned there was a disused PDP-11 that would need moved in time for a
forthcoming building refurbishment, and the rest, is, as they say, history.
I try to make sure that people around the campus know I'm interested in old
machines, and from time to time something interesting turns up :-)
I probably won't have much time to do anything other than gaze at it every
time I walk past, until the weekend, but I'll let you know how I get on.
I'm also trying to sort out the 6000VA UPS (unrelated acquisition) I got
last week, and mentioned on the list. I've got as far as getting it
powered up without tripping the 32A circuit breaker, getting the
diagnostics and status out of the serial port, and have figured out why it
doesn't like the batteries: the two sets of ten 12V lead-acid batteries are
all flat. None reads more than 0.2V :-( I presently have a pulse
generator/charger on some of them, to see if I can get any life out of a
few. It looks moderately hopeful.

Don't be ridiculous! I hardly ever use Usenet from this domain now that my

One good way I've seen to munch the address is...
